all concepts and notion of time and date are lost in a state of delusion. Much like Mindfuck, Timefuck is simply having all sense of time shaken up. States of Timefuck are usually achieved when an individual is on a holiday or camp.

In Chess, When playing a timed game and you know you are positionally, and materially at a unrecoverable disadvantage ( a loss is imminent) but you are far ahead in time' to make a crazy move for the sole purpose of mentally confusing your opponent. The end result is usually a win on time. Basically a Kamikaze suicide attack taking advantage of the clock

I was five pieces ahead in that game, but he 'timefuck'ed me with an unsupported kamikaze attack on my King by his queen. I lost on time.

time fuck is another word for a gay paradox.
If one person were to go back in time and have sex with him/herself, then it isn't considered gay because neither is masturbation, yet it is not masturbation because there is another person to have sex with, and it definitely isn't incest because they are not siblings.

If young Link and Link from Legend of Zelda Ocarina of time, had sex with one another, this would be considered a time fuck.
